#cattle breeding repeat

Repeat breeding is an expensive hitch at every level of dairy products, from small scale to large scale. It affects the profitability of dairy cattle, thus increasing the age at first calving in heifers, extending the inter-calving period each time insemination fails, and decreasing the calf crop at last.

A late repeater is a cow in which heat is observed later than 25 days after AI.

Anatomical

· Persistent hymen

· Cervical problems

· Ovobursal adhesions

· Uterine adhesions

Functional

· Delayed ovulation

· Anovulation

· Luteal insufficiency

· Failure of nidation of the fertilized ovum

· Excess of estrogen

Infectious

· Specific and non-specific uterine infections associated with fertilization failure or early embryonic mortality

· Clinical or sub-clinical endometritis

· Bacterial or mycotic endometritis

Managemental

· Improper semen handling

· Faulty AI technique

· Malnourishment

· Incorrect AI time

· Deficiency of energy

· Aged sperm and ovum

How to identify a Repeat Breeder?

Diagnosis of repeat breeding in cattle is itself a challenging task. Heat record maintenance is a must to find out whether a cow is an early heat repeater or a late heat repeater. Cows that have had three services and are not pregnant should be checked before serving again by a veterinarian.

Management tips for cows showing Repeat Breeding

The following guidelines are recommended if no specific cause has been identified.

1. Bringing the animal into positive nutritive balance.

2. Micronutrients and vitamin supplementation such as Se, Zn, Cu, Mn, and vitamin A, D, and E daily.

3. Use of good quality semen having more than 50 percent progressive forward motility.

4. Insemination of the cow at the right time of the estrum. AI twice at 12 to the 24-hour interval.

5. Proper AI technique.

6. After AI, clitoral massage or 100 micrograms of GnRH or 1500 IU of the luteinizing hormone can be administered to stimulate ovulation.

7. Skip the AI, administer 1 million units of penicillin in saline twice at 12 hours intervals during estrum.

8. Flushing the uterus with normal saline with moderate pressure to remove cellular debris or mild blocks in oviducts.

9. Sexual rest for two consecutive cycles and breeding.
